Even as billions in campaign funding saturate every known communication medium on the planet, there are apparently citizens — who know how to use Google — who have managed to remain blind to advertisements. For a hilarious take on low-information voters, check out this Saturday Night Live clip:

Before readers get too depressed, there are some credible studies in political science demonstrating that low-information voters may not harm representative democracies. University of Michigan Professor Arthur Lupia famously found that, on average, low-information citizens vote in similar ways to knowledgeable voters [PDF]. Ignorant voters can look to cues, such as political party or a trusted official, to effectively emulate the behavior of their better-informed counterparts.

Still, research in “Deliberative Polling,” where citizens are educated by experts on issues, finds that information can make a notable difference in public opinion. After hearing expert arguments on both sides about the Iraq War, for instance, more participants in the deliberative poll agreed that the Iraq War was not worth the cost (38 percent in the deliberation group thought Iraq was not worth it compared to 45 percent of those in a control group who did not receive expert education).

So, this raises the question: Why has our education system not stepped up and solved this problem?
